Add support for unicode characters

[Wouter Büthker]

I'm trying to run the gitinspector on my repository but it seems to fail because there is a contributor with a special character (ă) in her name

Hi @WouterButhker. Not a gitinspector issue. You don't have a an encoding that can show that character set in your terminal. This is why you get "unknown". There are other older issues that discuss this. #161 is one example.

In a nutshell, gitinspector will ask your terminal for the encoding. If the terminal can't map it this is the error you get. One solution is to redirect the output to a file (this will default to UTF-8).
